That always bugged me. Adaptation to the culture and environment will happen in some aspects. The practical life area using things like chopsticks is more needed here than it is in America, adding aspects of Taiwanese culture like a traditional tea ceremony would be wonderful (especially for elementary age), etc. But that phrase has almost always been used to excuse why they treat the materials as “a great way to learn (math)” instead of an aid to the child’s development.
That mentality has sadly also carried over to the training I have seen happen here. I actually saw a few people taking AMS training in Taiwan suddenly have a worksheet they were given for the pink tower. It was just ten squares of differing sizes on top of each other and the child had to color them pink. What purpose they thought it served, I can’t even imagine.
Previous schools I worked at hated how little extra paperwork I would give students and they always wanted more. Glad to be far away from that now. From my experience, the parents didn’t want that if you take the time to explain what is actually happening in the classroom and explain what benefits they WILL see. Because once they see the benefits the child is supposed to get, they see the system working.
